Here's an idea, open the page once, copy and paste into a Word document or similar, and then consult that whenever you want a smily. It obviously won't insert the thing for you when you click on it, but it'll at least have the correct code there for you. Just a suggestion, as someone who rarely uses smilies save for the generic ones (
and so on) I can't guarantee it'll work (i.e, the copy and paste may make things look odd, I don't know) but it should be cool. You're only worry will be having to check for newer ones (which are always at the bottom of the page), but at least it's a start.
